目的探讨小剂量多巴酚丁胺负荷超声心动图(LDDSE)预测存活心肌的价值及评价存活心肌的预后状况.方法 30例冠心病患者均行经皮腔内冠状动脉成形术(PTCA)或PTCA+支架术,术前1周内及术后(＞6周)用LDDSE观察室壁运动情况.结果 LDDSE预测心肌运动严重减弱节段血运重建后功能恢复的敏感性,特异性分别为72.7%和92.0%,预测无运动节段心肌恢复的敏感性、特异性分别为73.9%、79.5%,预测矛盾运动心肌节段敏感性、特异性为80.0%、90.0%.血运重建后双相反应型及持续减低型心肌运动功能显著提高.结论 LDDSE预测存活心肌有较高准确性,并可评估存活心肌血运重建后功能恢复情况.

Objective To detect survived myocardium by low-dose dobutamine stress echocardiography (LDDSE)and evaluate the prognosis of survived myocardium.Methods Thirty patients with coronary heart disease underwent Dercutaneous transluminal coronary angioplasty(PTCA)or PTCA plus stent.LDDSE was used to detect wall motion before and after operation.Results Sensitivity and specificity of detecting survived myocardium were 72.7% and 92.0%in hypokinesic segments,73.9%and 79.5%in akinesic segments,and 80.0%and 90.0%in dyskinesic segments respectively.The cardiac function was impoved significantly in patients with a biphasic response and a worsenjng resporlse during LDDSE after revascularization.Conclusion LDDSE is a safe and accurate method for predicting survived myocardium and its reversibility after revascularization.
